In 1986 , a New Zealander Hackett popularized Bungee as a commercialized sport of mass entertainment . This sport is very challenging . It is a test of people's psychological ability of endurance . Especially when descending , as if they are watching a fast forward tape and when they bounce back , they sway around . The timid people will shrink back at the sight of it . Even if they jump off , they find it hard to avoid screaming with closed eyes . No wonder people give the title ' brave ' to anyone who jumps off .   You see , the bungee participants take a deep breath when they stand at the starting spot and then , like diving , their heads are over heels and they jump off into the realm of the combination of heaven and earth . The wind roars at their ears and their bodies rapidly descend . They do not even have enough time to do several gymnastic movements and they are rebounded to the upper air by the cord .   Entrusting life to the care of a rope indeed requires infinite courage .   A young French fellow recalled his first bungee experience and said , " When I fastened the cord and walked to the platform , I was extremely nervous . When I looked down , I was nervous even more . If the cord had broken , I would be knocked to ' bakemeat ' . However , I knew my worries were unwanted . I was afraid if I retreated others might say something about me . I had to harden my heart and impose my head downward . I only felt wind wiring at my ears . My body rapidly descended . I thought that after only seven or eight seconds I was rebounded to upper air by the cord . In fact it was 30 seconds . Maybe because of my nervousness , I only felt seven or eight seconds . When rebounding to the high altitude , I felt a sudden sense of relief . I did not feel nervous very much , but very comfortable . "   It is hard to come by in life that you experience this kind of ' comfortable '
